(C1. 30-172) This invention relates to scrapers for wood, An embodiment of the invention'is illustrated glass, metal and like `substances. by way of example in the accompanying drawing Such scrapers, as hitherto constructed, comin which Figs. 1 and 2 are side and front views prise essentially a blade formed as a single piece respectively of a scraper having a double edged 5 of metal carried by a handle.

5 or in Fig. 6, the nut l2 is loosened on the bolt 1, the blades constituting the cutter thereby being rendered capable of adjustment on the bolt. One of the cutting edges of the cutter is then applied to the surface of the moulding with sufficient pressure to displace the blades to assume a position in which the cutter presents an edge of the same shape as the moulding. The nut I2 is then tightened to clamp the blades tightly together, whereaiter the scraper is available for use.

As will be seen from Figs. 5 and 6 of the drawing, the other edge of the cutter assumes a shape of opposite curvature and may be employed where it is desired to scrape a surface of that curvature.

If desired, some of the blades may be displaced to the full extent of their respective slots, leaving, for working purposes, a cutting edge of smaller breadth than the full breadth of the cutter.

It is to be understood that the scraper illustrated is shown by way of example only, the invention residingin the provision in a scraper of a cutter composed of a plurality of adjustable thin blades. Thus, the blades may be mounted on the handle by means other than that shown, while the blades may be of a shape different from that illustrated,

Also, the means for mounting the blades on the handle may be such that adjustment may be effected to permit of a varying number of blades being accommodated thereby. For example in lieu of the side portions 5, 6 rigidly attached to the yoke 2 illustrated in the accompanying drawing, adjustable sidermembers may be provided, the adjustment, for instance, being eifected by one or more set screws extending through the side members in such `manner that the side members may be retracted towards or projected from each other, 'their distance apart determining the number of blades that can be accommodated between them. Thus, with such an arrangement varying placed `when worn.

I claim: 1. A wood or the like scraper including a handle, a two armed yoke attached to said handle at one end and a cutter mounted on said yoke between the arms thereof and clear of said handle, said yoke comprising a central portion penetrating said handle at one end and presenting at the other a support for said cutter, and side members engaging said handle and said cutter, said cutter comprising a plurality of similar blades assembled together in abutting relation between said side members, and supported by said central portion in a common plane at right angles to the axis of and remote from the handle, and means traversing said blades and said side members to hold said ,blades clamped together, said blades providing collectively one or more adjustable cutting edges.

2. A wood or the like scraper including a handle, a yoke attached to said handle at one end and a cutter `mounted on said yoke clear of said handle, said yoke comprising a central portion penetrating said handle at one end and presenting vat theother fa support for said cutter and side members engaging said handle and said cutter, saidvcutter comprising a plurality of similar blades assembled together in abutting relation betweensaid side members and supported by said central portion in a common plane at right angles to the axis of and remote from the handle, each blade presenting at its extremities a pair of oppositely -disposedcutting edges, and means traversing said blades and said side members to hold said blades clamped together, said blades providing collectively .a pair of adjustable cutting edges.

3. A wood or/the like scraper including a handle, a two-armed-yoke `attached to `said handle at one end and ya cutter mounted on said yoke between the larms thereof and clear of said handle, Said yoke comprising a central portion penetrating said handle at one end and presenting at the other a support for said cutter, and side members engaging Ysaid 'handle and said cutter, said cutter comprising a plurality of similar blades assembled together in abutting relation between said sidemembers and supported by said central portion in a common planefat right angles to the axis of and `remote from the handle, and means traversing said blades and said side members to hold said blades clamped together, said blades being relatively adjustable transversely of the axis of said support and providing one or more adjustable cutting edges.
